Excited to share our publication on microbes in and on deep sea methane seep carbonates!
Rock-hosted ANME-SRB can be reactivated. Some rocks have a black ANME biofilm! The surface harbors diverse divergent particulate methane monooxygenases. Read here:

Distinct microbial communities within and on seep carbonates support long-term anaerobic oxidation of methane and divergent pMMO diversity
Abstract. At methane seeps worldwide, syntrophic anaerobic methane-oxidizing archaea and sulfate-reducing bacteria promote carbonate precipitation and rock

Women were historically excluded from health studies on the grounds that hormone fluctuations introduced "noise" into the data, and this has left us with a lack of understanding about a range of conditions

If someone tells you "we all have the same number of hours in a week" - ignore them
I spend 3+ hours a week, since 2013, exclusively on ankle pt exercises so I can *walk* every day. (Removing the pt time immediately after surgery)
We all have unique things but it makes our weeks unequal.

DEI is under attack, but the stakes are higher than many realize. Universities *must stand firm* in defending it. I lay out why in my latest piece for Nature.
Silence is complicity. Without DEI, we fail our students, our research, and our future.

Unusual ‘soda lakes’ may have kick-started life on Earth by concentrating key compounds
Phosphorus leached from volcanic rocks in warm waters could have triggered reactions needed to launch biochemistry

Finally read the below piece from Chanda Prescod-Weinstein, written in 2018 (not tagging intentionally, you can easily find her if you need ;). Exceedingly good and really makes me think about the way we've structured things at UC.
